通常情况下，linux下可以直接使用gcc命令直接编译生成可执行文件：
例如：hello.c
1 #include <stdio.h>
2
3 #define PI 3.141593
4
5 int main(int argc, char **argv)
6 {
7 printf("Hello world!
");
8 printf("PI: %f
", PI);
9
10 return 0;
11 }
可以直接用gcc hello.c -o hello即可生成可执行文件
也可以使用make hello也可生成hello可执行文件
那么你想看下分开编译的具体环节，请跟我来：
1、预编译：命令 gcc hello.c -E -o hello.i
gcc hello.i -S -o hello.s
结果如下：
1 # 1 "hello.c"
2 # 1 "<built-in>"
3 # 1 "<命令行>"
4 # 31 "<命令行>"
5 # 1 "/usr/include/stdc-predef.h" 1 3 4
6 # 32 "<命令行>" 2
7 # 1 "hello.c"

2、编译：命令 gcc hello.i -S -o hello.s, 结果：
